Secure Communication in Fog Nodes through Quantum Key Distribution

연구 분야: Cryptography

학회: International Conference on Advanced Network Technologies and Intelligent Computing

In this intensifying era of big-data, data processing is predominant. Data processing takes place closer to devices in the fog computing, strong security measures are necessary. The Hybrid Encapsulation Mechanism (HEM), Elliptic Curve Diffie-Hellman (ECDH), and Quantum Key Distribution (QKD) are furnished in this study as a safe method for authentic data sharing between fog nodes. HEM, a special encapsulation technique that makes use of the Advanced Encryption Standard (AES), is used to encrypt the data, and ECDH is used to generate the shared and private keys. A conventional route is then used to convey the data, which may offer a compromise between efficiency and security. But, fog nodes can communicate and exchange shared keys more easily over a quantum channel, which is an efficient quantum key exchange mechanism (QKD). ECC efficiently and rapidly generates encryption keys to safeguard data and these keys are impenetrable by even the most powerful computers due to their proven security. Along with safeguarding private information, this promotes collaboration and trust across fog nodes. The efficiency of the proposed method is calculated considering the execution time, computation cost, key size, and key strength. We discovered that our proposed approach outperforms existing ones when compared to them.
